Ua ulana ʻia nā geotextiles a i ulana ʻia i geotextiles. Hana ʻia nā geotextiles i ulana ʻia me ka polypropylene a me ka acrylic polyethylene siliki maʻemaʻe. Ma o ʻelua pūʻulu o nā wili like (a i ʻole nā ​​wili palahalaha), hele kekahi pūʻulu ma ka ʻaoʻao o ka ulana ma ka ʻaoʻao longitudinal (ka lole), a ʻo ka hui ʻē aʻe i kapa ʻia ʻo ka hoʻonohonoho hoʻonohonoho o ka weft. Hoʻohana ʻia nā mea ulana a me nā kaʻina hana me nā hui like ʻole e hoʻopili i ka pale a me ka weft o nā lole i ulana ʻia, hiki ke ulana ʻia i nā mānoanoa like ʻole a me ka compactness e like me nā pae noi like ʻole. ma mua o ka latitu), a he nui ka hana fluctuation. ʻO nā geotextiles i ulana ʻia: ʻike ʻia kekahi ma ke ʻano he geotextiles i ulana ʻia. ʻO ka ulana geotextile i ulana ʻia e pili ana i ka mea i kapa ʻia ʻelua ʻaoʻao. ʻElua mau pūʻulu o nā ʻili like ʻole he mau uea palahalaha, me kahi hui o nā kaula loʻi lōʻihi ma ka lom poepoe e hana ai i pūʻulu o ka ulana pōʻai pōʻai, e hoʻopuni ana i ka loom poepoe, a laila hoʻopili ʻia a lilo i lole. lole ulana. ʻO ka lole i ulana ʻia maʻamau i hana ʻia me ka polypropylene pp. ʻo ka mea i kapa ʻia ʻo geotextile i ulana ʻia he PP i ulana geotextile geotextile.
Ka ʻokoʻa ma waena o ka ulana geotextile a me ka ulana geotextile
ʻO nā huahana nui o ka ʻoihana he geotextiles i ulana ʻia. ʻO ka ʻōlelo kikoʻī o kēia manawa ʻo 2 T ~ 12 T i ulana ʻia geotextiles. Hoʻohana ʻia nā geotextiles i ulana ʻia e hana i nā ʻeke one a me ke one kai. E koho i nā lole i ulana ʻia me ka Kechong kiʻekiʻe a me ka ikaika kiʻekiʻe, i ʻole e holoi ʻia e ka wai kahe, a ke piʻi nui nei ke kūpaʻa ʻana. Hoʻoholo ʻia kekahi mau laulā koho o nā geotextiles i ulana ʻia e like me kēia: ʻekolu mau lom pōʻai pōʻai ʻeono nui, me ka laulā o 4 mika), a ʻo ka laulā o nā lole i ulana ʻia he 4 mika, ulana lole ulana 6 mika laula, ka mea hou i hookomoia 12 kaapuni poepoe wili 8 mika laula, i ulana ilikai ulana lole 8 mika laula, ʻO nā hiʻohiʻona waiwai geotextile i ulana ʻia: ikaika kiʻekiʻe, me ka hoʻohana ʻana i ka polypropylene ʻoihana ikaika kiʻekiʻe, polyester, polyamide fiber e like me nā mea maka, e like me ka decomposition me ka ikaika mua kiʻekiʻe, ma hope o ke ʻano o ka ulana ʻana o ka hale i lilo i kānāwai, hiki ke hoʻomaikaʻi hou ʻia ka piha piha, ka lōʻihi Decomposition o Hōʻike ʻia nā fiber kemika e ka denaturation ʻaʻole maʻalahi, decomposition, weathering, pili lōʻihi i ka hana kumu. ʻO ke kūpaʻa ʻino: ka ʻakika a me ka alkali kūpaʻa ʻana i ka fiber kemika decomposition, alkali kūpaʻa filament i ulana ʻia geotextile, moth hōʻoia a me ka mildew hōʻoia. Hiki i ka wai: ma o ka hoʻomalu pono ʻana i nā pores o nā lole i ulana ʻia, hiki iā ia ke hoʻokō i kahi pae o ka wai permeability.
Ka mālama pono a me ka lawe ʻana: ma muli o kona kaumaha māmā, hiki ke hoʻopili ʻia e like me kekahi mau koi, kahi kūpono no ka lawe ʻana, mālama ʻana, kūkulu ʻana, etc. 1. High ikaika plastic palahalaha uwea, i hiki pili i ka waiwai ikaika a me ka elongation ma muli o ka hoʻohana 'ana i ka pulu palapala; 2. Ke kū'ē i ka corrosion a me ka lōʻihi. ʻO ka ʻinoʻino o ka lepo a me ka wai ma nā kumu pH like ʻole; 3. ʻO ka ʻokoʻa ma waena o ka wai permeable flat wire a me ka wai permeable flat wire. No laila, loaʻa iā ia ka hana seepage wai maikaʻi; 4. ʻO nā microorganisms maikaʻi, ʻo ke kūʻē ʻana o ka microbial i ka moth ʻaʻole ia he kuʻikahi; 5. Maikaʻi ke kūkulu ʻana, no ka mea he māmā ka mea, palupalu, maʻalahi ka lawe ʻana, kau ʻana, a me ke kūkulu ʻana; 6. Hōʻike: 6 mau mika ka lōʻihi, I kēia manawa, loaʻa i nā huahana nui loa ka nui o kēlā me kēia ʻāpana o 100 – 600 g / ㎡.
2、 Ke kuleana o Geotextile i loko o ia mea: 1. ʻO ka hana o ka geotextile he multifiber: kahe ka wai i kānana i loko o ka papa waiwai, a me ka noi ʻana o ka lepo maikaʻi, filament nonwoven geotextile he maikaʻi ke ea a me ka wai permeability, ka wai, ka lepo. a invalid intercepting particles, one, liʻiliʻi pōhaku, etc., pili i ka fluctuation a me 2 o ka wai a me ka lepo 'enekinia, Ka noi o polyester ʻO nā mea i ulana ʻole ʻia a me nā mea kūkulu hale (e like me ka lepo a me ke one, ka lepo a me ka lepo, a me nā mea ʻē aʻe) me nā manaʻo like ʻole o ke ʻano (ka nui o ka particle, ka hāʻawi ʻana, ke kūlike a me ka nui, a me nā mea ʻē aʻe) e hoʻōki i ka hoʻokaʻawale ʻana, i nalowale ʻelua a ʻoi aku ka ʻikepili. ʻaʻohe hopena hopena, pili i ka hoʻolālā ʻikepili a me ka hana, a hoʻomaikaʻi i ka hiki ke halihali o ka hale. 3. He ikepili maikaʻi ka Geotextile e alakaʻi ai i ka wai, hiki ke loaʻa i ke ʻano o waho o ke kahawai wai wai, ʻO ka nui o ka wai a me ke kinoea o ka hoʻolālā lepo i vitro, ikaika kiʻekiʻe, hiki ke piʻi aku ma mua o 20 kn / M a me ka hana creep maikaʻi. pale ʻino. Hiki i ka hoʻohana ʻana o ka nilala geotextile ke hoʻonui i ka ikaika tensile a me ka pale ʻana i ka maʻi o ka lepo, hoʻonui i ka volatility o ke kūkulu ʻana, a hoʻomaikaʻi i ka maikaʻi o ka lepo.
